test case

The runtime has problems with generics at a depth of 3. Int64[][] seems to be working just fine. See the test case attached.

I'm running Mono 4.4.1 (Nightly Thu Jul 14 18:06:32 UTC 2016) on Arch Linux (up-to-date).

When compiled with csc/msc and ran against Microsoft .Net, the test case produces "foo\nbar". (expected behavior)
When compiled with csc/msc and ran against Mono, the test case produces "foo" and then crashes with SIGABRT:

  System.Int64[][][] doesn't implement interface System.Collections.Generic.ICollection<System.Collections.Generic.IList<System.Collections.Generic.IList<System.Int64>>>

  Debug info from gdb:

  Got a SIGABRT while executing native code. This usually indicates
  a fatal error in the mono runtime or one of the native libraries 
  used by your application.
